I will relay my favorite caddie story because it revolves around the 9th. Which by the way, is a GREAT hole on many levels. From the aesthetic to the challenge, everything about the hole is poster boy for why length of a hole, or pure length, is immaterial to quality gca.
A former pro baseball player was on the first tee. Introductions to caddies were made and this ball player turns to this well seasoned caddie and says " I don't want anything but yardage from you today." The caddie is fine with that. When they get to the ninth, this player has a birdie putt and at the last minute turns to the caddie and says "What'ya think?" The caddie begins to stalk the putt from all sides, and finally says "22 feet". The player says " No, No, what's it going to do?" So, the caddie does what everyone wants to do but few have the balls to do, he gave a sheit read and the player putted it off the green.
